Genetic variation in the needle flavonoid composition of Pinus brutia var. brutia populations

Biochemical Systematics and Ecology, 1998
In this paper, the variability of six Pinus brutia var. brutia populations was analyzed in relation to their needle flavonoid composition. In all trees, two proanthocyanidins: prodelphinidin and procyanidin, and six flavonols: myricetin, quercetin, larycitrin, kaempferol, isorhamnetin and syringetin were detected and measured by HPLC.

SEASONAL SECONDARY GROWTH IN NEEDLE LEAVES OF PINUS STROBUS AND PINUS BRUTIA

American Journal of Botany, 1987
Mature needles and elongating current year's needles of Pinus strobus growing in Massachusetts and P. brutia growing in Israel were collected monthly or bimonthly for seasonal analysis of leaf cambial activity. Mature needles produced secondary phloem but no xylem, and, regardless of the season, had a cambial zone from 2 to 3 cell layers wide.

Calabrian Pine (Pinus brutia Tenore)

1989
Calabrian pine (Pinus brutia Tenore) is native to the Mediterranean Basin, where, along with the Aleppo pine (Pinus halepensis Mill.), it constitutes large forests. However, Pinus brutia has a more restricted range and a more easterly distribution than Pinus halepensis (Dallmore and Jackson 1954; Davis 1965; MIrov 1967).

Genetic differences between Pinus halepensis, Pinus brutia and Pinus eldarica based on needle flavonoids

Biochemical Systematics and Ecology, 1997
A chemosystematic study based on needle flavonoids, was carried out on 324 trees from six populations of Pinus halepensis, six of Pinus brutia and one of Pinus eldarica. Two main flavonoid classes were identified and measured by HPLC: (pro)anthocyanins and flavonols.

Annual shoot growth components related to growth of Pinus brutia

Tree Physiology, 2002
Shoot elongation patterns of Pinus brutia Ten. were studied in six natural populations and 10 open-pollinated families within each population. The data were collected from a provenance-progeny trial that was thinned at Ages 13 and 17 years. Annual height increment was partitioned into first flush (spring shoot) and subsequent flushes (summer shoots ...

Adaptation of herbaceous plant species in the understorey of Pinus brutia

Agroforestry Systems, 2005
Most of Pinus brutia (Ten.) Holmboe forests are grazed, as silvopastoralism is well adapted in the Mediterranean environment. However, little attention has been paid to the demographic dynamic of the understorey vegetation even though it is strongly affected by the absorbed radiation.

Composition of gum turpentines of pinus halepensis and pinus brutia grown in greece

Journal of Chromatography A, 1964
Abstract Separate samples of gum turpentine Pinus halepensis and Pinus brutia grown in Greece were analysed by gas-liquid partition chromatography using two stationary phases of different polarity. It was found that the turpentine of Pinus halepensis consisted mainly of d-α-pinene (about 96%), while that of Pinus brutia contained less d-α-pinene ...

Untersuchung der Rindenextrakte von Pinus brutia Ten

Holz als Roh- und Werkstoff, 1980
Die Rinde von P. brutia ist reich an Extraktstoffen. Durch sukzessive Extraktion mit Losungsmitteln steigender Polaritat und mit verdunnter Alkalilosung konnen ca. 70% der Rindensubstanz herausgelost werden. Der Ruckstand besteht aus Holocellulose und ligninahnlichem Material.
